/**********************************************************
*
* Shadow Trail System v 1.1.1.7 by Maker
*
* Creates a trail of units behind the caster
*
* To use this system, copy this library,
* and then Table and CTL from Resources folder into your map.
*
* struct ShadowTrail
* static method add takes unit target, integer trailType, real duration returns thistype
* - target is the unit to attach the trail to
* - trailType, 0 = units are created repeatedly, 1 = uses the same units. Test which suits your spell better
* - duration is how long the trail lasts in seconds. 0 = lasts until the unit dies
*
* method setupMovingTrail takes integer count, real separation, real alphaFactor returns nothing
* - use this only if the trail type is 1, TRAIL_TYPE_MOTION
* - must be used if trail type is 1
* - count is how many units are in the trail. More units -> longer trail
* - separation is the distance between units.
* - alphaFactor is the transparency multiplier between units. The further away the trail unit is from the main unit,
* the more transparent it will be. Use values between 0 and 1.
*
* method setInterval takes real timee returns nothing
* - only affects trail type 0, TRAIL_TYPE_STATIC
* - must be used with trail type 0
* - timee is how often new units are created
*
* method setFadeRate takes real rate, boolean flatMode returns nothing
* - rate is how quickly the units fade out after the trail is terminated
* - flatMode == true, units fade at a constant rate. Transparency = transparency - rate. Try values around 10. Higher value, faster fading.
* - flatMode == false, units fade out at multiplicative rate. Transparency = transparency*(1-rate). Use values around 0.9. Lower value, faster fading-
*
* method setAnimationSpeed takes real r returns nothing
* - how quickly the animations of the trail units are played. Default value is 1.
*
* method setAnimationIndex takes integer k returns nothing
* - what animation index the trail units play
*
* method setColor takes integer red, integer grn, integer blu, integer alpha returns nothing
* - sets the colouring of the trail units. Use values between 0 and 255.
* - if alpha is 0, the unit is completely transparent, 255 means it is fully visible
*
* method setEffect takes string model, string attachPoint, boolean attachToShadows returns nothing
* - attaches a special effect to the trail units and the main unit
* - model = the path of a effect to attach
* - attachPoint is the attachment point
* - attachToShadows, if set to true will attach the effect to the trail units and the main unit, if
* set to false then the effect is only attached to the main unit
*
* method remove takes nothing returns nothing
* - destroys/removes/ends the trail
* - you can use this to remove the trail before the duration ends.
* - trails are automatically detroyed when the duration ends so there is no need to use this
*
* method setPlayerColor takes playercolor pColor returns nothing
* - Sets the player color of the dummy units
*
*
* Examples
*
* / --------- Moving Shadow Trail ----------
* local ShadowTrail ST = ShadowTrail.add(GetTriggerUnit(), TRAIL_TYPE_MOTION, 8) // Lasts 8 seconds
* call ST.setupMovingTrail(5, 20, 0.85) // This method affects only trail type 1, must use
* call ST.setAnimationIndex(2) // Recommended to set
* call ST.setFadeRate(10, true) // Optional method call, recommended
* call ST.setAnimationSpeed(1.0) // Optional method call
* call ST.setColor(200, 200, 200, 200) // Optional method call
* call ST.setEffect(EFF, "chest", false) // Optional, EFF = variable holding the model path
*
* ---------------------------------------- /
*
*
* /--------- Static Shadow Trail ----------
* local ShadowTrail ST = ShadowTrail.add(GetTriggerUnit(), TRAIL_TYPE_STAITC, 8) // Lasts 8 seconds
* call ST.setInterval(0.06250) // This method affects only trail type 0, must use
* call ST.setAnimationIndex(6) // Recommended to set
* call ST.setFadeRate(7, true) // Optional method call, recommended
* call ST.setAnimationSpeed(1.0) // Optional method call
* call ST.setColor(200, 200, 200, 200) // Optional method call
* call ST.setEffect(EFF, "chest", false) // Optional, EFF = variable holding the model path

Always liked these things.
Hmm, what do you know? I have to spread rep before giving you some. I really don't visit this site often o_o

Hmm.. interesting
But i have a question
could this cause some lags?
And.. While the unit's trail is being created, could we change the trail in the middle of it (using different model or different animation,colors,..etc)?

You have been extracting some brain juices now huh 
The fading is a bit not smooth,or perhaps its just me
anyways, I LIKED IT
edit
Because of that,I have some dilemmas forming if im going to make footprint system or just ignore it
edit edit
Map name is wrong

Update
v1.0.0.1 @ 22.02.2013
-Fixed a bug that caused permanent trails not be terminated with remove method.
-Using setEffect method now destroys the old effect.
I had 6 units running with the trail and saw no FPS drop at all.
You can change the colour and animation on the fly, but if you have to change the model then destroy the existing trail and create another.
Did you test the map or only look at the video? The video is only 30 FPS.
You can configure the fading speed with setFadeRate method and you can configure the number of trail units/how often they spawn, how far away they are from the caster and each other, and how transparent they initially are. All these affect the fading effect.

Recompile the map, you've got vJass still in the script so it doesn't run.
• It looks odd when you suddenly stop moving with a 'moving trail' and your trails instantly become invisible. Especially when turning. It'd look better to fade it out over a small duration or have the trail approach back in to the source.
• You can't configure the playercolor of the units in the trail?
• I might have missed it since I can't stand to read code using CTL, but it doesn't seem to check for when a unit is removed (unit type id == 0).
• I reckon you should set those
• You could probably assign the shadow trail types to constant keys such as TRAIL_TYPE_STATIC or TRAIL_TYPE_MOTION.
• Typo in this part with 'time':
• Out of curiosity, how do you spell colour/color where you are from? I spell it as 'colour' but I usually just name things 'color' in public codes.
• I think 'attachToShadows' or 'attachToTrail' would probably be more descriptive than 'toShadows'
• I don't think you really need SAFE_X or SAFE_Y options, you can just hide the units and store them anywhere really.
• Perhaps allow the option of which player the units are created for.
• Also allow modifying the unit trail so you can apply things to them. For example, adding abilities or effects. You could then not have to use dummy units for hero trails. You can create trails using the hero id under a neutral player and just add 'Aloc'. But that would look weird with the shadows on the units. Just an idea.
Although I'm not sure whether doing something like is going a bit too far on such a system like this whose purpose is quite basic.

BJDebugMsg calls to show when debug mode is on only.• You could probably assign the shadow trail types to constant keys such as TRAIL_TYPE_STATIC or TRAIL_TYPE_MOTION.
• Typo in this part with 'time':
JASS:
.
* method setInterval takes real timee returns nothing
* - only affects trail type 0
* - must be used with trail type 0
* - timee is how often new units are created
JASS:
.
* method setColor takes integer red, integer grn, integer blu, integer alpha returns nothing
* - sets the colouring of the trail units. Use values between 0 and 255.method setEffect takes string model, string attachPoint, boolean toShadows returns nothing• I don't think you really need SAFE_X or SAFE_Y options, you can just hide the units and store them anywhere really.
• Perhaps allow the option of which player the units are created for.
• Also allow modifying the unit trail so you can apply things to them. For example, adding abilities or effects. You could then not have to use dummy units for hero trails. You can create trails using the hero id under a neutral player and just add 'Aloc'. But that would look weird with the shadows on the units. Just an idea.
Although I'm not sure whether doing something like is going a bit too far on such a system like this whose purpose is quite basic.

Update
v1.0.1.1
-Trail type 1 now fades out if the unit stops moving instead of instantly disappearing
-Now correctly removes the trail if the main unit is removed from the game
-Added global variables for trail types
-Using setEffect method now destroys the old effect and applies a new one
It now fades out.
No. I set it to default to neutral passive. I might add something so it is configurable.
You are correct, UNIT_TYPE_DEAD doesn't cover a situation where the unit is removed from the map. Added unit type id check.
I did have them but they were taken away at some point. Added them back.
Good idea, added.
Not a typo, there's a struct member called time set in the method, I used timee in the parameter to circumvent overlapping names.
I live in Finland and have been schooled by teachers who taught British English.
Yeah, changed.
Actually hiding/unhiding makes units with locust selectable. That is why I tried to avoid those, and used safe coordinates. But I just realized that I can always add Locust again. I got rid of safe coordinates.
Maybe, but not for now.
I want to avoid having shadows on units. But I know a way to create units without shadows. Hmm, going to test a bit.
Also if the units are created for neutral passive then they will start to run back at the point they were created at after 10 seconds, I'll try to get around that.

Try again with the latest JassHelper.
Fair enough.
Then I think perhaps it'd be for the better to use safe coordinates. Or perhaps set the scaling to 0. Apparently hiding/unhiding/adding locust would be costly compared to simply SetUnitX/Y.
Can you pause them so they don't?

Did you try saving my map, did that work? Is the problem only in the map you imported the system to?
Did you copy CTL and Table libraries?

Oh hey I can't save your map either... Hm...

v1.0.1.2 @ 23.02.2013
-The dummies are now set to ignore their guard position so the AI won't try to move them if they go to far from where they were created
The dummies are now created for neutral passive. I tried creating them with GetUnitTypeId(caster) but then they are still considered as obstacles even with locust and collision turned off. So a dummy unit type is needed.

v1.1.1.2 @ 23.02.2013
-Now doesn't require dummy units to be created in object editor
-Users can configure the dummies to use the team colour of the owner of the main unit or alternatively neutral passive
I was an idiot. When creating a unit based on the unit type id of the main unit, pathing is checked. Only after that Locust is added. The solution is to set the x and y of the unit after adding Locust.
I also managed to make the shadows of the dummies not to show. Ignoring guard point doesn't work for heroes, so I pause the dummy instead. It will still play animations correctly.
No need to create extra dummy units now in object editor, which is great.
Now the only issue is the extra foot prints created by the dummies, but I can live with that.

It looks odd when the moving trail is faded out from the set alpha value instead of the alpha value they're currently at.
Also, your map needs to be recompiled and reuploaded (again).

v1.1.1.5 @ 25.02.2013
-Shadows now fade in and fade out more smoothly in motion trail type
-Removed unnecessary code
-Added setPlayerColor method which sets the player color of the dummies
Thanks, should be fixed now, both issues.

Set the duration parameter to 0:
set ST = ShadowTrail.add(targetUnit, TRAIL_TYPE_STATIC, 0)Being transported makes the trail to not show up so no issues there. Teleporting causes no issues either.
This got me to realize that the trail will reveal the location of hidden units. I'll do something about that.

Looks good now except for one more thing which I'm not sure is a result of the shadow trail system or the jump system. Using jump seems to screw up the unit pathing calculation. If you use jump and make a 180 degree turn (so move behind you) the unit will do a little circular turn. The normal case is that the unit will simply turn on the spot and move.

That is due to the units created not having locust when they are created. The solution is to create them at some other location, add locust and then instantly move to where they should be. Thanks for reporting, I might not have noticed that myself.

It is a bit problematic. Adding Ghost ability removes footprints, but then other players can't see the trail units. I could use a dummy unit type in object editor, but I don't want to

Footprints are created by the model itself . either you uses a dummy which its not relevant with this system or you just remove the sfx animation from magos.

Maker! I found a leak. Not a very important one, but I have to test my leak finder on something.
Never mind. This is just your example code...

Hey Maker,
Quick question about this cool system. My model has special effects attached, say armor, helm and weapons, ect. These obviously are not part of the original model file. Can you provide a method of linking any special effects via external triggers to the dummy trail units?
Maybe a hashtable?
thanks

Luckily there already is the seEffect method, that allows to attach effecs to the trail units. Unfortunately currently you can only create one effect on them, and the effect is created on the main hero also. But with some modifications, it could work like you want to. I'll see if I have the ime and motivation to make this change.

Look at the examples in the documentation part. Change
You should also destroy the trail when the unit dies (if it will not be revived) or is removed from the map. You can store the trail as an integer.

What an awesome spell you got there, but I completely don't understand how it works, I'm kind of noob in triggering, but I want this one so much, can you make it in GUI...? I'll really appreciate it...

Is there a way to make this apply also when your attacking rather just moving or is that impossible?
